2018 ATS Sedan

For 2017, Cadillac has revised the trim structure of the ATS to follow the larger trim hierarchy found throughout the company's other models. Beyond that, the CUE infotainment system has been updated and is now standard in all ATS models. It includes new functions with apps like Pandora, the Weather Channel and iHeart Radio. Inside, the instrument cluster has been restyled, while under the hood, the base 2.5L engine has been discontinued on sedans.
